• Strengths:
  • The solution correctly implements the in-order traversal to validate the BST.
  • The time and space complexity are optimal.
  • The code is clean and easy to understand.
• Areas for Improvement:
  • The comment at the top of the file (ValidateBst.kt) mentions the problem of constructing a binary tree from preorder and inorder traversals, which is unrelated to the current problem. This should be removed or corrected to reflect the actual problem being solved.
  • While the use of a class-level variable (prev) is fine, it could be encapsulated better within the helper function to avoid potential side effects in a larger codebase. However, this is a minor point and does not affect the correctness or efficiency of the solution.
